This application discloses a DAB converter and its driving control method. The method includes: obtaining the voltage transfer ratio based on the input voltage and output voltage of the DAB converter; obtaining the feedforward power based on the input voltage, voltage transfer ratio, and output current of the DAB converter; obtaining the primary-to-secondary side shift ratio based on the input voltage, output voltage, voltage transfer ratio, input current, and feedforward power of the DAB converter; obtaining the primary-side inward shift ratio and the secondary-side inward shift ratio based on the voltage transfer ratio, feedforward power, and the primary-to-secondary side shift ratio; and driving the DAB converter based on the primary-side inward shift ratio, the secondary-side inward shift ratio, and the primary-to-secondary side shift ratio. This invention optimizes the values ​​of the primary-side inward shift ratio, the secondary-side inward shift ratio, and the primary-to-secondary side shift ratio using relevant parameters of the DAB converter to achieve precise driving control of the DAB converter. By adjusting the control parameters of the DAB converter, the soft-switching range can be expanded, current stress reduced, and light-load efficiency improved, while significantly increasing the system's energy conversion rate.
